you can walk into a walmart, buy a supermarket cart full of ammunition, pay for it, walk out, no questions asked. and so, all i'm suggesting is we should do background checks when people buy ammunition as well. >> it's a fair point. you talk about certain categories of people can't buy guns, which seems to be part of the problem because when ever there's a mass shooting, it becomes clear to normal americans these people are very sick. they are mentally ill. they haven't been institutionalized, there's been no way to find these people, but yet, they clearly are, to whatever extent you want to say, mentally ill. what can we do about that? >> here are a couple of points. first of all, someone who buys, for example, 1,000 rounds of ammunition or more, is probably someone who should be of interest to local law enforcement. >> fair point. >> at some point. >> yeah.
